Asked by ..

The IT director has requested that you verify that traffic to a new server from her machine goes only where it is supposed to and can't be redirected to another IP address. You decide to attempt to manipulate traffic on the network to see if things are really secure.

You have pulled up Ettercap and plan on using one of the plug-ins for testing.

Which of the displayed plug-ins should you use? remote_browser


isolate


dns_spoof


scan_poisoner

Use dns_spoof.

Reason: dns_spoof lets Ettercap answer the target's DNS queries with attacker-controlled IPs, so you can redirect the director's machine from the real server to another IP to test whether traffic can be rerouted. Note this requires you be in a Man‑in‑the‑Middle position (ARP poisoning) so the target's DNS queries go through your host.

Quick notes for testing:
- Ensure you have authorization.
- Put a mapping in Ettercap's DNS file (e.g., /etc/ettercap/etter.dns): "newserver.example.com A 10.0.0.5".
- Enable the dns_spoof plugin in Ettercap and perform ARP poisoning between the target and gateway.
- Verify from the director's machine with nslookup/ping that the domain resolves to the spoofed IP.

Do not run this on networks or machines without explicit permission.
